need schematic for a emud model t7.....

[mike68]

Hey, I recently purchased a emud model t7 radio. I have a problem with the power supply and cant quite figure it out without a roadmap. any help would be appreciated. I had the radio playing fine and all of the sudden just a hum. I have replaced the 3 section filter cap, but now am getting just around 147 volts on the b-plus where before the hum problem I was getting around 300 volts. any thoughts? thanks Mike
